Question

Two satellites X and Y revolve in the same circular
orbit around the earth. The mass of X is greater
than the mass of Y. Which of the following is
greater for X then Y?
(a) Speed only
(b) Speed and gravitation force only
(c) Potential energy and gravitation force
(d) Kinetic energy and gravitation force​

Answer 1

Answer:

C D both are the answers I think

Answer 2

Answer:

The correct option is (c) and (d). When two satellites X and Y revolve in the same circular orbit around the earth having a mass of X greater than the mass of Y. Then the potential energy, kinetic energy and gravitation force will be greater for X than Y.

Explanation:

• The energy that is held in any object or system as a function of its position or component arrangement is known as potential energy.
• In contrast, kinetic energy refers to the energy of moving particles inside a system or an item.
• Both, potential energy and kinetic energy are affected by mass.
• As the mass of the object increases, potential as well as kinetic energy increases.
• It can be understood by the equation,
• Potential energy = gravitational potential × mass of the satellite
• Kinetic energy = 1/2 gravitational potential × mass of the satellite
• Gravitational force is also affected by mass.
• The gravitational attraction between two objects grows as their respective masses do as well.
• The force of gravity between two things doubles if one of their masses doubles. If one of the items triples in mass, the gravitational pull between them will also triple.

Thus, when two satellites X and Y revolve in the same circular orbit around the earth having a mass of X greater than the mass of Y. Then the potential energy, kinetic energy and gravitation force will be greater for X than Y.
